Why don't PAE vs PT (Total Power) measurements agree?

Hello,

I'm tuning an NXP LDMOS FET model in Microwave Office.  When my Vds current is about 20A at 12V, my output power on port 2 measured by the "PT" Total Power measurement shows ~100W (which is our optimization target).  

Here is the part I don't understand:  Why does PAE show about 75%?    Shouldn't 100W/240W have a PAE of ~41%?

Port 1 (Pin) is 17dBm, so 0.050 Watts, a negligible amount. 

(Pout-Pin)/Pdc == (100-0.050)/240W == 0.416.

What am I missing here?

Thanks for your help!
